Application filed April 7, 191a. Serial No. 759,4ae.

vented a new and useful Improvement in Vulcanizing Apparatus, of which the following is a full, clear, and exact description,

reference being had to the accompanying drawings, forming part of this specification, in -which-- Figure 1 is a View partly in side elevatlon and partly in vertical ,section of oneform of apparatus embodyingmy invention; Flg. 2 is an end view of the same; Fig. 3 1s a plan view of a portion of the machine; Flg. 4: is a transverse section; Fig 5 is a detail sectional View; Fig. 6 is a detail view showing a modification of a portion of the apparatus; and Figs. 7 and 8 are detail views showing difierent forms of for the boiler.

My invention has relation to a vulcanizing apparatus, and more particularly to apparatus for use in patching and repairing rubber boots and shoes.

The object of my invention is to provide apparatus of this character, which is simple and convenient in its constructlon; by meansof which a piece or patch may be applied to and, vulcanized to any portion of arubber boot or shoe; and to provlde simple and efi'ective means for obtaining the necessary heat and pressure for complete vulcanization.

The nature of my invention will be best understood by reference to the accompanying'drawings, in which I have shown a pre ferred embodiment, and which will now be described, it being premised that various changes can be made in the details of construction and arrangement of the parts without departing from the spirit and scope of my invention as defined in the appended claims.

In these drawings, the numeral 2 designates a supporting stand of any suitable character and having mounted thereon a boiler 3 for the generation of steam to supply the necessary heat for the vulcanizing operations. This boiler may be heated by any suitable arrangement of burners, such as indicated at 4 and supplied either by gas or gasdlene. In the machine illustrated I have shown the burners as adapted to be supplied with gasolene from a tank 5.

top attachments In accordance with my invention, I provide a boiler 3 with a plurality of projecting hollow supports for the articles to be vulcanized, each of these supports having means for conveying steam therein; and also havlng means in connection therewith for applying the. necessary pressure to the article on the supports. The different supports are arranged to facilitate the opera tions upon diflerent parts of aboot .or shoe.

For vulcanizing pieces on the rear por tion of a boot, I provide the projecting hollow support or horn 6, which communicates at its inner end with the interior of the boiler 3. Extending within this horn to a point near the outer end thereof is an escape pipe 7 for the steam, having a pet cock 8 at its inner end which communicates with the atmosphere. The pipe 7 and pet-cock 8' also provide simple and efiective means whereby, the heating of the horn may be localized, by controlling the escape of the air trapped within the horn. Thus, in some in the manner shown in dotted lines in Fig.

1, and the patch is held thereon by means of clamping devices. These devices are shown as consisting of a flexible strap 9 arranged to be passed over the horn in the manner shown and having its ends attached to a nut 10. The necessary pressure is applied to this strap by means of a handled screw 11 having a threaded bearing in the nut and a fixed hearing at its end against a portion 12 of the frame. At the opposite end of the machine is av hollow horn or projection 13 having an upwardly curved end portion adapted to fit within the toe or instep portion of a boot, as shown in dotted lines. Below this horn or support 13 is a fixed frame member 1+1, and at either side thereof is a frame member 15 or 16, each of which has an end portion hinged at 17.

18 is a clamping device similar to that before described. In working upon the upper portion of the toe of the boot, this clamping device is arranged as shown in Fig. 1.,

its handled clamping screw 19 hearing against the lower projection 1a of the frame. If it is desired to apply a patch to the side portions of the boot, the clamping device will be applied to one or the other of the projections 15 or 16 in the manner shown in Fig.3, the hinged portion of the projection at the opposite side being turned bac as indicated in full lines in Fig. 3.

Projecting from one side of the boiler and communicating with the interior thereof, is a hollow support or horn 20, particularly adapted for work on light or low cut rubber shoes. The shoe may be placed in various positions on this horn, one of such positions being illustrated in dotted lines in Fig. 2. It is provided with a clamping de vice 21 similar to those before described, the handled clamping screw 22 thereof having a bearing against a fixed arm 23. I may also provide the support 20 with the yoke 24 carrying a screw clamp 25 by means of which a heel piece '26 may be clamped against and vulcanized to the heel of the shoe. In most instances, however, in vulcanizing heel and sole pieces prefer to provide separatemeans, such as best shown in Fig. 4. This arrangement consists of a plate 27 removably seated on the top of the boiler 3 and having suitable depressions therein for the heels and soles of one or more boots or shoes. For obtaining the necessary pres sure, I provide the clamping members 28 and 29, actuated by the screws 30. These screws preferably have their bearing in nuts 31 carried by the hollow frame or casing portion 82, whieh is secured to the plate 27 to be removable therewith. The nuts 31 are preferably adjustable in slots so as to enable the clamping members to be brought into the most effective positions. By the provision of the removable plate 27', the

' tachment for placing soles on boots.

piecesto be vulcanized can be properly placed in theplate 27 while the latter is cold and the clamps applied thereto, after which the. device can be placed on the boiler. This is a feature of great practical value, since the work can be accurately fitted and placed while the parts are cold, thus greatly facilitating the work. The parts can also be cooled before the work is removed. In Fig. 7 I have shown a form of this top attachment in which the plate 27 has a cavity 27 which is shaped to receive and apply a wedge-shaped patch 27 to a worn boot-heel. In this case the clamp 28 is adapted to pass'down within the boot-leg. Fig. 8 illustrates another form of top-at- In this form-the clamps have padded buttons or clamping members 29 which press upon the top of the boot toes. I may also provide the heater witha horn or support 34, at the opposite side'thereof from the born or "support--20, this horn having an upwardly curved portion adapted to hold a shoe while vulcanizing the patch on the front part of the upper. 35 designates the clamping band for this horn or support.

Fig. 6 shows a modification of the horn shown at 20 in Fig. 2. It differs from Fig.

2 only in the shape of the horn 20, which extends upwardly from its connection with the heater.

It will be apparent from the foregoing that my invention proy'ides vulcanizing apparatus which is simple and inexpensive in character, and by means of which the vulcanizing may be done upon any desired part of a boot or shoe. It will be obvious that the heater may be provided with a variety of difierent forms of horn or support other than the particular forms which I have illustrated, thereby adapting the machine to a still wider character of work. It will also be obvious that instead of generating the steam directly within the steam chamber of the apparatus, steam may be supplied thereto in any suitable manner.
